11 tooth cog

[James Nagy]

My new chain is slipping on the 11 tooth cog. It works fine on all other gears. It's all cleaned up and derailer adjusted. After looking closely at the cog it does look like the valleys on the cog are deeper and wider then the other gears and the teeth do look somewhat narrower. My question is are the shimano 11 tooth cogs all the same as being universal? This is on a 9 speed Juiced rip current.

If it is a regular cassette, then you can get a 11t 9-speed cog. But that’s on a regular cassette. I don't know if it is a freehub. https://worldwidecyclery.com/collec...hUxWBtl9xSTQSKLGheQtqzpw95nQdr9rFrwGXvYOeZfqH
but you need to know what cassette you have.

It's a free hub. I went ahead and ordered the whole cassette because mine does have some rust in area's and the cost to replace all instead of just one gears isn't that much. Thanks for your input.

I have worn out many 13t cogs on the tandem. The 11t sometimes, this last time a 15t. Some of those can be replaced when you hit the bigger ones. You’re stuck on cassettes.

Brand new chain, Adjusted. You've done all you could. Replace the gear,

I hate when I put on a new chain and I get skipping. On the tandem, it’s really a pain. So I try to have all the replacement cogs on hand. We can wear out a 13t in 2 to 4 thousand miles.

Probably the best approach.

If you haven't worked on a cassette before, there are special tools available to make the process easier and avoid damage:
